Specification of Letters Patent.

Patented Ap1i121, 1908.

Application filed August 21, 1907. Serial No. 389,486.

.To `all whom it may concern:

Be it known that I, ANTONI Gwonnk, a

lsubject of the Emperor of Austria-I-lungary,

planer adapted to be so adjusted that if desired the same set of knives will make one depth of cut as the hoard enters the machine and another depth as it leaves the machine,

thereby making a finishing cut ai ter thc -first or deep cut has heen completed.

It is also an object of the invention to provide a planer in which the knives revolve in a horizontal plane, so that the knives enter the material from the side and cut a shaving of uniform thickness, thereby considerably reducing the power required for operation.

It is also an object of the invention to provide a planer having a bed or table section at each end which are independently adjustable, so that the work may be adjusted to receive a different depth of cut at one end of the machine than it does at the other.

The invention consists ofthe matters hereinafter described in the specification and more fully pointed out and defined in the ap. ended claims.

-n the drawings: Figure l is a view partly inside elevation and partly in vertical section of a device embodying my invention. Fig. 2 is a top plan view of the device. Fig. 3 .is an enlarged detail of the adjustable bearing for' the knife carrier. Fig. 4 is a plan View of the bracket for said bearing. Fig. 5 is a fragmentary section of the knife 2. Fig. 6 is an enlarged perspective view of one of the knives.` Fig. 7 is a side elevation of the drive shaft. Fig. S is a fragmentary side elevation of the attaching means for the drive shaft and knife carrier.

As shown in said drawings: a frame A of lany desired form, construction and material is provided, and on its top are the. bed or table sections B and B', each of which forms one half of the table. Said sections are inde pendently adjustable vertically of the machine, and any preferred means may be provided to accom )lish the adjustment. AS shown however the frame is provided at each side and near each end thereof with track rails C, each of which is provided with two inclined surfaces c and c which incline upwardly and towards the center of the machine. Each of said rails is provided intermediate saidinclined surfaces with a post C, the upper end of which fits in a suitable socket c on the under side of the table section and acts to prevent longitudinal movement of the section while permitting vertical movement thereof. An adjusting frame, indicated as a whole by D, is slidably engaged on said rails at each end of the machine, and the top thereof engages against bearing surfaces l) on the under side of the table section. The side members of said adjusting frame are provided on their under sides with inclined surfaces complemental with the inclined surfaces c and c', and are adapted to slide thereon, so that as said adjusting frame is moved longitudinally of the machine it acts to raise or lower the table section, dependent upon its direction of movement. Any preferred means may be employed to operate said frames, but as shown, adjusting screws E are journaled at their outer ends in the end flanges of the table sections and at their inner ends are journaled in flanges or lugs e on the under side of each section. Said screws have threaded engagement in the end members c4 of said adjusting frames and when rotated act to move the frames longitudinally of the machine.

For the purpose of locking the table sections in adjusted position each is provided with locking shafts F and F the former of which is engaged at lits upper end to the under side of the section near the inner end thereof 'and extends down through the frame A, and is provided with a nut f beneath said frame. The latter F extends upwardly through the bottom yof said frame A and has threaded engagement with the section intermediate the sockets c, Said table sections are each provided at their'inner or contiguous ends with a central, semi circular apertui'e for vthe knife carrier G which is adapted to rotate therein in a horizontal plane. Beneath said aperture are upper and lower pairs of transverse beams indicated respectively Aby II and I-I, and on said beams, in axial alinement with said aperture, are the split bearings II and H, one half of each of it into the carrier. Said knife carrier is provided in its top with a circular recess and seated therein is a retaining plate l, which is provided at its center with a shaft i extending downwardly through and beneath the shaft G, and is provided on its lower end with a right and left hand thread. A bracket l having four radially directed arms i which turn upwardly at their ends, as shown in Figs. 3 and 1, is engaged beneath the beams H by means of bolts i2 extending therethrough and into said beams and by means of the shaft i which is threaded therein and is provided with a nut beneath the same. A bearing plate 13 is supported on said bracket by means of set screws i3 and is provided with an aperture therethrough in axial alinement with the bore of the shaft G and through which the shaft i extends. The lower end of the shaft G is shaped to form one member of a clutch and seated on said bearing plate is a rotative bearing plate I4 which is also shaped to form one member of a clutch and is engaged to the lower end of the shaft G so as to rotate therewith. The knives J are arranged on the knife carrier near its periphery and extend therethrough a sufficient distance to give the required cut. Said knives as shown more clearly in Figs. 5 and 6 are slotted at their lower ends and engaged to the carrier in a forwardly inclined position by means of set screws j. The shavings fall through the knife apertures in said carrier and are carried outwardly from the machine by the inclined slides K. On said table sections B and B are the abutments L and L which act as guides for the boards or other timbers being operated upon and hold them in place for the knives to act against. Said abutments are provided with laterally directed slotted lugs Zwhich are bolted to the sections and permit adjustment of the abutments to and from the carrier.

The operation is as follows: Vhen the section B at the feed end of the table is below the edges of the knives, and the other section is flush with the knives the cut will be all at the feed end of the machine. Vhen it is desired to make a shallow or finishing cut at the other end of the machine the section B is slightly lowered so that the edges of the knives project slightly above the same and by reason of the board springing down onto the same the `knives will produce a slight cut. Vhen either of the sections is to be adjusted it is released by means of the shafts F and F may be varied without departing from the principles of my invention l claim as my invention:

1. rl`he combination with a main frame, of independently adjustable table sections thereon, a knife carrier adapted t'o revolve ,in a horizontal plane, a plurality of knives proj ecting upwardly therethrough, a tubular shaft projecting downwardly from said carrier, a removable bearing plate on the end of said shaft, an adjustable bearing beneath said plate, a bracket supporting said bearing and means extending through said shaft and bracket adapted to hold the shaft firmly on the bearing.

2. rlhe combination with a main frame, of table sections thereon, means for inde endently adjusting said sections, a vertica tubular drive shaft, a knife carrier on the top thereof adapted to revolve in a horizontal plane, a bracket beneath said shaft, an ad justable bearing thereon for said shaft and means extending through said shaft andv bracket adapted to hold the shaft on said bearing.

6. The combination with a main frame, of a vertical drive shaft journaled thereon, a vertically adjustable bearing plate beneath the lower end of said shaft, a bracket adapted to support said plate, a knife carrier on the upper end of said shaft, means extending axially of said shaft and connecting said carrier with said bracket, and vertically adjustable table sections on said frame.

7. The combination with a main frame, of cross beams thereon, bearings on said beams, a vertical tubular shaft journaled in said bearings, a bracket engaged on the beams beneath said shaft, a vertically adjustable bearing .plate thereon adapted to support the shaft from beneath, a knife carrier on the upper i l l l end of said shaft, a retaining plate thereon, l
